Jon left for a two day busines...

Jon left for a two day business trip to Chicago. He was only a few blocks away from his house when he realized he'd left his plane ticket on top of his dresser. He turned around and headed back to the house. He quietly entered the door, walked into the kitchen. He saw his wife washing the breakfast dishes, wearing her skimpiest negligee.
She looked so good that he tiptoed up behind her, reached out, and squeezed her left tit.
"Leave only one quart of milk," she said. "Jon won't be here for breakfast tomorrow."

Johan August Brinell

Born 21 Nov 1849; died 17 Nov 1925 at age 75.Swedish metallurgist who devised the Brinell hardness test, a rapid, nondestructive means of determining the hardness of metals. Brinell studied many aspects of iron and its production. Brinell´s important work on transformations in steel during heating and cooling. His discoveries about the control of the carbon containing phases is the present basis for the knowledge about properties of steel. The Brinell Hardness Test measures the relative hardness of metals and alloys, by forcing a 10mm hard steel ball into a test piece with a 3000kg load for 30 seconds and measuring the surface area of the resulting indentation. The load is reduced to 500kg for very soft materials and the steel ball is replaced with tungsten carbide for very hard materials.
